Which mistakes? OL has been bad both years, but was also under CNS.
Two years ago, we lost to a bunch of teams we were able to get revenge on this year (except OU in the regular season).
Two years ago, we couldn't complete a short pass, but excelled on long ones; this year, it was almost the opposite.
Two years ago, we had a running QB; this year, it was a throwing QB, who eventually got beaten up.
The defense improved immensely from the 1st year. It was good enough to win a NC if the offense had come together.
Now, in hindsight, the only game that's hard to explain is the opener against FSU. In SECCG against Georgia, we had no chance with the injuries. Now the game against IU doesn't look as ridiculous since they did the same with Oregon.
Someone on X has even said Alabama may have been the 2nd best team in the country behind IU. I don't believe that, but I also don't believe we have necessarily regressed and made the same mistakes as year 1 either.
